How to add a date to a PDF
Quick answer: To add a date to a PDF, open it in a PDF editor, choose Add text, tap the date line or the spot next to your signature and type the date, for example 11/03/2026. Match the size to the form, drag it into place and download. If the form has a date field, just tap the field and type.

Almost every form that needs a signature also needs a date: leases, permission slips, invoices, timesheets, medical forms and agreements. Getting the date in the right place and the right format is a small thing that saves a returned form.
This guide covers how to type the date, how to place it next to a signature, which format to use, and what to do when a date field refuses your input.
Add a date to a PDF with Quick PDF
- Open the PDF Sign in at quickpdfapp.com, open Add text to PDF (or the editor) and choose your document.
- Find the date line Scroll to where the form says Date, usually beside or under the signature line. Zoom in so the line is easy to hit.
- Type the date with Add text Tap just above the line and type the date in the format the form asks for, such as MM/DD/YYYY.
- Match the size and colour Choose a size similar to the printed labels. Black or dark blue looks right next to a signature.
- Add your signature if needed Tap Sign, draw, type or upload your signature and place it on the signature line next to the date.
- Download the dated PDF Tap Download or Share to save or send the finished document.
Which date format to use
Use the format printed on the form. Many forms show a hint like MM/DD/YYYY under the line. If there is no hint:
| Format | Example | Common for |
|---|---|---|
| MM/DD/YYYY | 11/03/2026 | Most US forms |
| Month D, YYYY | November 3, 2026 | Letters, contracts, agreements |
| YYYY-MM-DD | 2026-11-03 | International and technical documents |
| DD/MM/YYYY | 03/11/2026 | UK, Europe and many other countries |
Writing the month as a word avoids confusion when the document goes abroad, because 03/11 means March 11 in the US and 3 November elsewhere.
Dating a document you sign
The date next to a signature usually means the day you actually signed. Use today's date unless the document tells you otherwise. Some documents also have separate dates, such as a start date, a move-in date or a period covered; read the label beside each line so you put the right date in the right place.
If several people sign, each person dates their own signature. If you are signing someone else's prepared document, only fill in your own lines. For more on signing, see how to sign a PDF without printing or signing a lease electronically.
Date fields in fillable forms
Fillable forms sometimes have a real date field. Tap it in Fill PDF form and type the date. Some date fields are set up by the form maker to accept only one format, so if a date is rejected or rewritten, type it exactly as the hint shows, including slashes or dashes.
If a field will not take your entry at all, place the date with Add text just above the field instead. The printed result is the same.
Adding dates to many pages
Timesheets, logs and initialed contracts often need a date on every page. Quick PDF does not stamp a date automatically, so you type each one. To keep it quick and tidy:
- Type the first date, check its size, then use the same size for every page.
- Place each date in the same spot so the pages line up when printed.
- If each page also needs initials, add them with Add text in the same pass, or use Sign with a typed script name.
Other ways to add a date
- Mac Preview: add a text box from the Markup toolbar and type the date.
- iPhone Markup: tap plus, then Text, type the date and drag it into place.
- Microsoft Edge: Add text lets you type on PDFs on Windows.
These are fine for a single date. A full editor is easier when you also need to fill other blanks, sign, or correct something on the same form.
Troubleshooting dates on PDFs
- The date overlaps the label. Drag it to the right or lower the size a step.
- The date is on the wrong line. Tap it and drag it, or delete it and type again.
- You typed the wrong date in a flattened form. Cover it with White-out and type the right date on top.
- The form shows a different date after you send it. Some fillable date fields reformat entries in certain viewers. Choose Flatten form when downloading so your answers become part of the page.
Questions people ask
How do I insert a date in a PDF?
Open the PDF in an editor, choose Add text, tap where the date belongs and type it. Adjust the size and drag it so it sits neatly on the line. If the form has a fillable date field, tap the field and type the date there instead.
Can I date and sign a PDF at the same time?
Yes. In Quick PDF you can place your signature with Sign and type the date with Add text in the same session, then download one finished file. Put the date right next to or under the signature, where the form asks for it.
Should I write today's date or another date?
Next to a signature, the date normally means the day you signed, so use today's date. Other date lines on the form, such as a start date or date of birth, ask for something else. If unsure, check with whoever sent you the document.
What date format should I use on US forms?
Most US forms use MM/DD/YYYY, such as 11/03/2026. If the form prints a different hint, follow the hint. Writing the month as a word, such as November 3, 2026, avoids confusion on documents going abroad.
Can I add a date stamp to a PDF?
Quick PDF has no automatic date stamp, but you can type the date with Add text, make it bold, choose a colour and draw a box around it with Shapes so it looks like a stamp. You can also insert an image of a stamp with the Image tool.
How do I add a date to a PDF on my phone?
Open quickpdfapp.com in Safari or Chrome, open the document from Files or Downloads, choose Add text and tap the date line. Type the date with the phone keyboard, drag it into position, then share or download the file.
